First if you still have a balance due on the return after the unemployment correction then you have until MAY 17th to make the payment.  The IRS will be recalculating the already filed returns with unemployment on them  sometime in May ... to see the new balance due or refund then open the filed return and look at the bottom line.  When you open the return the program the correction  will be made automatically.

• Log in and at the Tax Home or in the section "Your Tax Returns & Documents" for 2019, look for a link "Add a State."
• Click on "Add a State."  (you don't really add one.  That's just to open your return back up.)
• After the return is open, click in the left menu column on TAX TOOLS, then PRINT CENTER.
• Then choose "Print, save, view this year's return."
