I filed yesterday and found out that I entered the wrong type of IRA on my return. I have a simple Ira, not a traditional Ira. Do I need to amend?

Yes, you probably should Amend your Return.  If your Simple IRA is connected with your Business, it may affect Schedule C and your tax return.

Contributions to a SIMPLE IRA are not to be entered anywhere under Deductions & Credits.  If the SIMPLE-IRA plan is through your employer who issues to you a W-2, enter amounts shown in box 12 of the W-2 only in box 12 of TurboTax's W-2 form, nowhere else in TurboTax.  If you did otherwise, you must amend.
