I am not however getting any height channels coming through the Dolby calibration files. I have tried almost every possible routing to see if something is down mixing them to 5.1. I Do see the "ATMOS" logo on my receiver saying it should be running,
If the receiver says it's receiving Atmos, that implies that the audio is being bitstreamed and you certainly should be able to hear the overheads if the soundtrack you're listening to includes them. In that case, I really dunno what would be keeping your overhead speakers silent other than a glitch or defect in the receiver. My comments below are mostly generic.
You might try doing a full return-to-factory-settings reset (several in a row) and then do another receiver setup, using the Assistant and selecting the option which includes the maximum number of possible speakers, more than you actually have. During the tests it'll disable the ones it can't hear.
To double-check, if you press the Info button on the receiver's remote, while you're playing an Atmos soundtrack, the receiver's on-screen informational display should show the word Atmos in the left-hand (input soundtrack) channel display and the icons for all of your speaker channels should be lit up in the right-hand (output speaker) channel display.
and have tried all of its mix modes.. so I don't think this is the result of having "all channel stereo" selected. What am I missing?
When the receiver is decoding an Atmos soundtrack, all of the speaker channels are in use although some of them might be silent, so selecting +Surround or +Neural:X won't actually do anything. Other options (like Stereo) should downmix the audio.

Atmos test files run off of my TV usb drive player. It is a Samsung JU6400 4K UHD Smart TV Audio passed through HDMI, via bitstream PCM Line compression HD Audio. No Height channels
As JD wrote, if the receiver reports that it's receiving PCM (multichannel) audio in its Info display, then it is not (and can not) receiving Atmos. In that case, you can check your overhead speakers by pressing one of the Music/Movie/Game buttons on the remote and scrolling down to an entry that says either +Surround or +Neural:X. Both of those settings upmix the incoming audio to use overhead speakers. How much activity they actually get depends on the soundtrack.

Whether or not you can get Atmos by way of a computer depends on the media player software that you're using and its audio settings.
- try to plug USB into Marantz. it won't play video files only audio
Although this won't help fix your problem...
In many cases if you ignore the receiver's warning, you can still play a video file and hear its audio although the receiver can't decode and display the video.
I have run blurays that have atmos- but they are too "busy" to calibrate and really see if Atmos is working correctly.
Any ideas? does every way I try to play it compress the bitstream to non ATMOS before sending it to the receiver? is it the HDMI?
In general, the most reliable way to get Atmos audio with video is to play a disc, USB or DLNA signal through a Blu-ray disc player. Some models of TV can now forward Dolby Digital Plus soundtracks from some streaming services, though.
