If you e-filed, make sure the return was e-filed successfully and accepted:
Re-check your e-file status
Make sure to enter the federal refund amount without the state refund, less any TurboTax fees if you chose to pay any fees out of the refund.
If you are married filing jointly try using the Social Security Number for the name that appears first on the return.
If you have already tried the above on the IRS WMR website, you can check the status of your refund by calling the IRS Refund Hotline at 800-829-1954.

I believe the problem was caused by Turbo Tax. When I entered in my return how much I had received in stimulus money, Turbo Tax said I was owed more and said my refund would be $3,143. IRS.gov is saying the refund amount is wrong. Tonight I loaded Turbo Tax and it updated the program. Now it is saying that I can expect a refund of $1,943.
How much will this delay my refund?
Should I do an amended return? I tried and TT said that there is some work still being done by the IRS regarding amended returns.
No. Wait until you receive your refund to see exactly how much you receive. If there are calculation errors, IRS will automatically correct them and send the correct amount.
If there is an issue after you receive your refund you can check to see what provisions have been made for the Recovery Rebate Credit which is Stimulus check. If you need to amend, IRS will let you know.
