You didn't give the source of that answer, other than "on this board," but it's wrong. Here's a link to the TurboTax Online forms availability list for New York.
New York Individual Form Availability
If you look at Form NYC-202 in that list you will see that it is available for printing, but in the E-file column it says "unsupported."
If you get a PDF of your tax return with all forms, schedules, and worksheets, the Form NYC-202 should be in there. I'm not familiar with the details of printing from TurboTax Online, but here's an FAQ on how to get a copy of a return after you have filed.
How do I get a copy of a return I filed this year in TurboTax Online?
If that doesn't include the NYC-202, go into your return, go to the Print Center, and select the option to print with all forms and worksheets. (I'm not sure of the exact wording.) If you have trouble with that, someone who knows more about printing from TurboTax Online will help you.
