Why does Turbotax call my $3,000 special 403(b) catch up provision an excess contribution, when it is valid for those >50 and with >15 years of employment?

Turbotax doesn't recognize this special situation.  As I recall, nothing bad happens if you ignore the warning, so just ignore the warning.

Thank you!

Opus 17 is correct.  TurboTax developers failed to program TurboTax to accommodate 403(b) special catch-up contributions, so you'll just have to ignore the warning.

Thanks!
