I figured out what David from TurboTax was referring to in his response. The error is showing up in FORMS MODE on the Sec 179 Limit form not on the Form 4562. If you click on Form 4562 on the left menu of forms you will see that LINE 10 is not populated with the prior year carryover number. I had to populate line 10 and line 12, then go into the box below Line 11 and populate it as well. Once you populate these lines the error on the Sec 179 Limit page will go away.
