It depends. You may be filing the wrong tax return if you or your wife are exchange visitors for the year. If you are considered a nonresident of the US, you should file a 1040-NR which TurboTax does not support. If you need to prepare a 1040-NR, you can use Sprintax which is a partner of TurboTax.
This may be the reason for the discrepancy in the tax payment amount.
