I just got stuck with this due to having two K-1 (mine + my husband's) for the same partnership so it lists them separately (wouldn't let me efile when I deleted the redundant 2nd listing of same partnership, insisted that I link to a worksheet I deleted to try to avoid this issue, so I had to divide the real QBI by 2 so not double-counted) and forced me to aggregate them with an aggregation statement that was not explained in the error message and seemed to ask me twice so I wrote the same explanation twice only to discover that it wasn't that it had rejected my first explanation due to too many characters and wanted me to try again, but instead was asking a different question, whether it had changed from the prior year, so I didn't answer the 2nd question, just repeated the first statement more succinctly, and now it's too late to fix since it didn't display the changes it was making unbeknownst to me before filing. Total BS.
