I don't know that in the history of the forum, that i have ever disagreed with @IRonMaN  , but I would go back and amend the 2019 and mark final.  I would fear some computer at the offices of Irving R. Shyster would generate that dreaded non-filing penalty for 2020 return.  The penalty is $210 for each month or part of a month (for a maximum of 12 months) the failure continues, multiplied by the total number of persons who were partners in the partnership during any part of the partnership's tax year for which the return is due. So, if you get that, you are going to spend time resolving that...and good luck getting it resolved via mail.
