I'm unable to reproduce any indication by 2019 TurboTax that $18,500 contributed to a 403(b) along with $18,500 contributed to a 457(b) that there is an excess contribution. What version of TurboTax are you using and in what step in step-by-step mode are you getting an indication of an excess contribution?
