On form 8615, I have been rejected twice for "Reject Code FDI_8615Line7Box_Err". The initial message said "Please update the Federal 1040 product on or after March 19th, 2020. Then, please re-submit this return electronically." I deleted both the 1040 and 8615 forms and refilled them on the 19th only to be rejected again. Any word on a fix?
