After you file

2/22/20201 update for NJ:  go back and change your choices to ONLY e-file your 2020 Federal 1065 Business Partnership return.  (Check the box that you'll e-file your 2020 State NJ New Jersey 1065 Business Partnership return later.)  I WAS able to file my 2020 Federal Business Partnership return and it's been accepted. (Yea!) However... I'm still getting the above error message for my 2020 New Jersey 1065 Business Partnership return.  I suspect because:

a) NJ is still messing around and hasn't finalized their 2020 e-filing system yet so I need to keep trying 

OR

b) to cut costs the state of NJ took away the option of e-filing this year and you have to mail in your Business partnership return for 2020.
