I didn’t make any changes since I filed. And neither did the IRS. I spent an hour and a half on the phone with Turbo Tax today and what they ultimately told me is that they can make changes in their system and it essentially recalculates it based on those changes. This can all happen after you file. But they don’t notify you that this happens nor do they try to amend. So the 1040 that is available on the site now has the newly calculated numbers (not the amount of your original filing). And they (TurboTax) keep no record of the 1040 that you filed at the time of your original submission. So...unless you happened to download and save the 1040, it’s lost forever. TurboTax said the IRS transcript should be the official record. I’m sure that’s true, but not helpful when trying to get a mortgage and they need to crosscheck your 1040 with the amount you paid to the IRS. I’m absolutely shocked that TurboTax is aware of this gap and has not fixed it.
