efiling PA State tax

I tried to efile my federal return three times but three times were rejected for the same reason (there is a potential issue with the calculation of your taxable inherited IRA). Turbotax said that it was IRS issue. I followed Turbotax recommendation to mail in my federal return. Now I wanted to efile my PA state return but I cannot because I did not efile my federal. I spoke to my PA state return folks. They said I can efile my PA return after I mailed in my federal return. It is not PA that does not allow efiling. Is there a bug in the turbotax program? What can I do beside mail in my state return?
