I have a walk in cooler charged with 404a with a tev and has a Copeland scroll compressor .noticed system kept clicking off on low pressure so proceeded to add some Freon and forgot to invert my can so I charged with a vapor on suction side . Realizing my error shut down system ,recovered charge ,put on new filter drier and then pulled vacuum and proceeded to charge with can inverted had closed king valve on receiver and charged through liquid side .Wondering what damage I may have done and if I need to do anything else like change the TEV

Don't think much of any damage was done. Txv should be fine. Does it seem to be operating correctly?
