Assuming your figures are correct, you should have an excess of $567. The allowable family maximum for 2023 is $7750, and you contributed $7700. That extra $50 you have under this year's cap should be applied to the prior year excess, leaving you with a current excess of $567.
You may have entered something incorrectly. Remember that workplace contributions are only entered from your W-2 -- turbotax gets them automatically from box 12 with code W. So double-check your W-2s. When you are asked if you made any additional contributions, only enter out of pocket contributions you paid directly to the HSA bank, not workplace contributions. Also check to make sure that you have told the program you both had qualifying HDHP coverage all year.
Did you enter that you each had a $617 excess? For purposes of this calculation, you should assign the excess to just one of the HSAs.
Other than those checks, you would need to look at the program internal worksheets to see if you can find what went wrong. If you are using the desktop program you can switch to forms mode but if you are using turbotax online, you need to call customer support so someone can look at the internals of your tax file.
