There are several things that adjust wages: IRA contributions, combat pay, etc.
You can review what is affecting your total by going to the worksheet form:
on the top left of the desktop format, you can go to View; Forms; 1040 Individual; Earned Inc Wks.
This shows a worksheet that recaps all earned income and the adjustments that are made to it. You can print it if needed. Hope this helps.
It depends. You may want to print your return before you file. You have access to all forms when you choose to print your return in TurboTax Online/Mobile. However you are required to pay before printing, but do not have to file until you are ready.
If you are using TurboTax Desktop you can switch to Forms and review all forms and worksheets.
If you still have questions please update here and we will help.
