Q. "Did you make money in any other state?" Do I answer No, since technically I only made my money in the state of New York?
A. You answer No.
Q. If I answer "No" then how do I file with Connecticut?
A. You file a non resident CT return to get a refund. You may want to considered mailing in your CT return, so that you can attach an explanatory statement.
Q. The Help section (https://ttlc.intuit.com/turbotax-support/en-us/help-article/printers-printing/file-nonresi[product k...) says to "enter 0 for the amount of income earned in that state" to get a full refund. Can I do this even though box 16 on my W2 shows a positive number?
A. Yes. It's a workaround to get the info on the CT return. On the CT line, put CT in box 15, 0 in box 16 and the CT withholding in box 17. On the NY line, add the CT box 16 amount to the NY amount (assuming the NY box 16 didn't already have the full year amount).
