The NYC Employees Retirement System (NYCERS) is not in the list of tax exempt 1099-R sources. It is NYS taxable in TurboTax when it is state tax exempt. How to fix?

TT automatically enters Box 2a amount in Box 14. It is blank on my 1099. If I make blank like 1099, it doesn't transfer properly to state return. Very confusing and frustrating design.
