After you file

@MadiHerm Sorry you're in the same boat.

I received a letter from the IRS that includes a voucher to mail my payment. The voucher references the "letter number" assigned to me and other info including my social#.

 

There's a sentence "If you need any forms, schedules, or publications mentioned in this letter, you can get them by visiting our website at www.irs.gov/forms-pubs or by calling toll-free at 800-TAX-FORM 800-829-3676.

Also there's a note that if you have questions, you can call 877-766-2161.

 

Hope that's helpful to you. Take care!
