When submitting my completed 1041Return for Estates and Trusts for e-file keeps giving me three errors. This return is for calendar year 2020, but it prompts me to fill in beginning date, ending date, and year of return like this was a shortened year. Wither I leave three places blank, or put in dates and year, gives me the same error. Will not let me file electronically. How do I fix so I can file electronically?
