My employer over withheld my 2018 Roth IRA contribution. Can I correct for " ..elected deferrals is more than allowed" W2 Summary Sheet (line 12) error in TT?

My company corrected the over withholding, but did not provide an adjusted W2.  Since I have to put the correct W2 figures in on my return I keep getting  the TurboTax error and cannot file electronically.
