I was able to file the Fed Tax 1041 separately - with the 8453-FE attached, but electing to pay tax due by check (manually). As I recall, this worked last year, so something has been screwed up for 2023. HOWEVER - I have not yet been able to file the Wisconsin Form 2 electronically despite electing to pay tax due by check.
IT IS OUTRAGEOUS that this problem exists. Just saying.
