You should do what Bsch4477 said in the first reply above, but do it with the CD/Download TurboTax software, not TurboTax Online. With the CD/Download software you can prepare your federal tax return without the dependent and save it. Then use Save As to save a copy of the federal return with a different name. Add the dependent in the new copy, prepare the New York return in that copy, and save it. You now have two saved files, one for the federal return without the dependent and one for the state return with the dependent. You can e-file the federal return from the first file, and print and mail the New York return from the second file. (It's okay to file the New York return by mail.) Save PDFs of both files for possible future reference.
Doing it this way allows you to retain saved copies of both the federal and state returns that you actually filed.
In TurboTax Online you can save only one set of federal and state returns. The most recent returns would be saved automatically. There is no way to exit from TurboTax Online without saving.
