I signed up for installment. i dont want it. how do i cancel it? i gave the wrong telephone number. How do i correct it?

[Opus 17 · Accepted solution]

If you transmitted your tax return and it was accepted by the IRS, then you cannot do anything about your installment plan request until the IRS sends you a letter.

If you have not yet filed, you can go back through the file interview and change your answers before you finally transmit your return.
