After you file

@XZ123 

 

DO NOT AMEND UNTIL the IRS has processed the initital return.  It is possible they adjust whatever you are going to amend in any event.   if you paper filed, it'll be 6-9 months from the time you filed until the IRS processes your return as it is woefully backlogged. 

 

if you are due a refund from the State, then there is no urgency to file (other than to get the refund).  I'd wait to complete the state return until after the IRS situation is settled as most states begin with federal income as its starting point.
