Tried numerous times to enter license code at end to finish and file. What to do if license code for TT Deluxe is "not valid"?

Your best bet is to contact TurboTax support.  See the TurboTax Help article How do I find my license code for TurboTax Desktop? for guidance. 

Although you're not actually missing your license code, the article contains contact information you can use to address the issue.
