I have multiple (15) state income taxes paid as result of my partnership;how do enter ALL online for federal and state? (It seems the online version limits state entries)

TurboTax Online lets you prepare and file (electronically or on paper) up to five state returns per federal tax return.

If you need to prepare returns in six or more states, consider the TurboTax CD/Download software instead. Although the software only lets you e-file up to three states per federal return, you can prepare and paper-file as many states as you want.

Tip: When preparing returns in multiple states, it's best to do your nonresident and/or part-year resident state returns first, and your resident state last.

The other issue you need to make sure you understand is whether the partnership has filed a composite return on your behalf or if they just remitted withholding.

This is key, as if the partnership filed a composite return on your behalf, then you do not need to file a return; the partnership has done that for the eligible nonresident partners.
