Last week I was able to roll over isolated files from 2019 to 2020 no problem.  Now when I try to roll over single files from 2019 to 2020 it gives me an error message in 2020 that says “invalid format”.  It leaves 2019 fine but doesn’t get into 2020. I'm hoping it's just a glitch right now - we need to do this with some files for Q4 estimated tax payments . . .
