We have the same situation! I spent over an hour on the phone with Turbo Tax on Friday explaining that their "fix" on 4-4-19 only covered the regular over-50 catch-up provision (which is $6K) but not the second catch-up option for certain government plans when the employee is in their last three years, which allows 2x the annual amount ($37K in 2018). The person I spoke with on the phone understood what I was saying and she looked up the IRS Publication that explains it but when she was tried to tell her supervisor, that person insisted that the problem was already fixed and no more updates would be forthcoming.
I received an email from Turbo Tax this morning telling me that the issue was on my end and was not a problem with their program so I will now have to print and file a paper return.
Guess I won't bother paying the money for Turbo Tax next year since we'll have the same situation again and they don't seem to want to fix their software to accept the larger contribution amount. Frustrating!!
