Same for me. I detached from 8915F, partially followed the instructions, which meant going back to 2020’s return for the info, and refilled out 8915.
I checked against the 1st 8915 I’d done 2 days ago and it looked as it should. There were a couple of blanks in the form that were different than the one that was rejected. Resent it and already have acceptance from IRS.
