The irs states I didn’t file and I have email confirmation that I did.

Did you receive a notice? 

Submit whatever evidence you have to the Service.

Or maybe it’s that you didn’t pay the tax due?

 What email did you get?   When you efile you get back 2 emails.  The first email only confirms the transmission.  The second email says if the IRS (or state) Accepted or Rejected your efile.  And check your spam folder for them.

When you log into your account you should also see the status and if it was Accepted or Rejected, Started, Printed, Ready to Mail, etc.  What does it say?

Even though you have an email confirmation if the IRS does not have your taxes, you need to get it to them.  Print and mail the return.  The cover page will have a list of what documents to include.  Make sure you sign the return in ink and that you use a mailing service that tells you when it has been received.

And---if you owe tax due---your only proof that you paid will be your own bank or credit card records.

 If you have federal tax due you can pay by mailing your payment with the 1040V voucher, (which has the address printed on it, having the payment taken out of a designated bank account, or you can pay directly on the IRS website.

You must pay your state tax due using the state’s preferred method of receiving payment.  For most states that will be by making a payment to the state’s own tax website, or by mailing a check or money order.
