Retirement tax questions

Yes, the software indicates I need to Fix my information because I have exceeded the $30K limit.  My hr retirement coordinator indicates because I am over a certain age and have more than 15 years service with my employer I am allowed an additional $3K catch up (for a limit of $33K).  Do I just file my taxes and wait for IRS to question it? Seems like Turbo Tax should allow me to enter information that would prevent a later IRS inquiry.
