Retirement tax questions

The IRS clearly states that 457 (b) plans (code G) allow for a 3 year catch up contribution of up to $37,000 for people who have reached plan retirement age as I have.  As of today (Monday, April 8), I am being flagged by TurboTax that I exceed the $24,500 limit AND WON'T ALLOW ME TO FILE ONLINE!  PLease fix this.  I ran the update available as of 4/7/2019.  I paid for everything requested, including Audit protection.
