How can I e-file with excess deferrals over the contribution limit showing on form W2/W2G Summary?

Unable to e-file with excess elective deferrals to qualified plans on my W2/W2G Summary form.  Shouldn't this be a warning and not an error?  I have accounted for the excess deferral as income so the taxes are correct, but I am still unable to e-file.  The TurboTax Home & Business is stuck in a loop telling me that I have over contributed above the $18,500 limit.
