Trying to efile but Turbotax will not let me because of SC tax paid greater than the SC tax income made. Looking for work around

While working in OH last year the payroll company also taxed me in my home state of SC.  Since travel days were the only work considered as SC income my resulting W-2 has my SC income at 1/3 of the income tax paid to SC. Because of this Turbo Tax is telling me I have to file by mail, but since I have to file in 5 states and also file a Sch C, I would prefer not to mail in my returns.  Does anyone know a work around to allow me to efile?  

I have double checked this against my pay stubs and this info is correct.

Thanks!
