HI, Ryansarn:
I'm in the same boat as you're. Last year, I mailed a whole set of returns because I couldn't e-file Form 6765. This year (2021), we are going to try your way (e-mail the core part and mail Form 6765 and 3800 plus 1120 if necessary). I wonder, if your way worked last year? Could IRS match your e-filled documents with your mailed in documents easily without any questions? Please advise. Thanks!
