How do I transmit the form when program flagged my 457 deferral amount when it matches my W2 and my plan allows more than the $24,500 the program is checking for?

The limit for my 457b deferral is a special 3-year catchup through my State employer for employees within 3 years of retirement and doubles the normal deferral limit. My deferral is within this limit, but Turbo Tax is flagging it as an error and will not let me transmit my forms electronically. What can I do to fix this problem?
