I have a very similar situation. My former employer withheld NY taxes in 2020 because I paid a small amount of tax in 2019 due to work travel to NY. @LenaH , I went through similar process as you described to indicate 0 work days in NY. All was fine when I entered the numbers, but in the Review section it was flagged as an error and TurboTax won't let me e-File with NY State unless my number Outside of New York work days is less than my total work days.
Specific Numbers:
Total Days Employed = 83
Non-Working Days = 34
Work Days Outside of New York = 49
Any advice?
TurboTax is demanding that I use a number less than 49 and will not continue with the e-File process.
