@pinkypie asked: "How do I prove To the IRS that my payment was fully paid and I do have my bank statement to show."
What kind of payment and what tax year?
There must be more to the story. Why are you needing to prove something? Did you get a bill/notice from the IRS for something you already paid? If so, is there a phone number on it to contact that department at the IRS, so you can ask them what form of proof that they want?
