don't know what you would be missing for 2019 since all reporting forms for you should have been issued by now. if you're sure you're getting a state refund, I would wait to file. the return is already late it was due 4/20/2020. what about your federal return? to e-file the state return the federal return must be e-filed. it was due 7/15/2020 with any payment.
Thanks so much. I hav gottn pretty much the same general advice locally: Wait and file with the proper documentation. Te federal was efiled on time, but will need to be amended, also with the docs. Mahaloz
