Received CP3219A and agreed to changes. Realized later that the number they provided was higher than it should be. Can i file 1040x or do i have to pay full amount now?

I received a CP3219A notice last year about a deficiency in my tax returns. I responded by saying I agree to the the return to the changes. I recently received a Cp22a of the total amount I owe and it is billed on my irs.gov account as part of a balance that I owe. I found out after the fact thatthe number I owe is not accurate. I do owe money, but the liability is MUCH less than It says on the notice. Can i still file a 1040x to get the money back, or am i stuck because i agreed to the changes in the CP3219A notice?

Yes, you can file an amendment to the agreed upon amounts since you have new information.  In order to do this, you will need to first create a return in TurboTax that shows the information in your return as you agreed upon it with the IRS.  Then, you will create an amendment for that return.  Be certain to mail copies of your supporting information to the IRS along with the amendment.  Here is a link to the instructions to Amend My Return in TurboTax.
