After you file

@paulwegweiser Another suggestion---if there is a phone number on the letter---assuming it is a CP80----call the IRS.   Or use this method to call the IRS:

 

To call the IRS:IRS:  800-829-1040  hours 7 AM - 7 PM local time Mon-Fri

Listen to each menu before making the selection.

First choose your language. Press 1 for English.

Then do NOT choose the first choice re: "Refund", or it will send you to an automated phone line.

Instead, press 2 for "personal income tax".

Then press 1 for "form, tax history, or payment".  

Then press 3 "for all other questions."

Then press 2 "for all other questions."  It should then transfer you to an agent.

 

 

 

 

And/or check your online account with the IRS.
