How do i change the mailing address after following instructions?

You can edit your address in MY INFO.    Use your current address----the address you want the IRS to use if they need to mail you a letter or a check.

 

 

 

 Or did you already file the tax return?   If you already filed you can send a change of address to the IRS:
