I paid my taxes by direct debit in turbo tax Monday, but my efiled return was rejected can I or do I need to change the paymethod since i need to mail the return?

If your return was rejected then the "direct debit" information was not transmitted to the IRS.  If you still want to e-file, tell us the rejection code or rejection message you got and we may be able to help you get it e-filed.  If you want to mail it instead, you can pay by mailing your payment with the 1040V voucher, having the payment taken out of a designated bank account, or you can pay directly on the IRS website.

TurboTax will not know anything about your mailed return, and will continue to show “Ready to Mail” on your account.  TurboTax will not know that you put your tax return in an envelope and took it to a mailbox.  TurboTax does not get updates on mailed  (or emailed) returns.

When you mail a tax return, you need to attach any documents showing tax withheld, such as your W-2’s or any 1099’s.  Use a mailing service that will track it, such as UPS or certified mail so you will know the IRS/state received the return.
