If my employer didn't put my overtime wages on my w2, can I use the info on my paystubs to enter the "half of the time amd a half" for the deduction
Hello DEW1,
Yes, you may use your year-end payment summary or paystub to get the OT to enter the half time for time and a half. See this article for details.
