Can't e-file because of TT error on federal form: Passive Operating Loss ...sum of losses in individual years shouldn't be greater than the total loss. How to resolve?

The amount I entered is correct, however that figure was mistakenly entered additionally to last year's losses and to the line item "...prior to 2018" thereby triggering the error message. TT loops me to the review page to fix it, but there is no way to fix it, and because of this I cannot e-file, which is frustrating being that I paid a significant sum for such conveniences.
