Get your taxes done using TurboTax

Sounds like your state return has been submitted to NY.  Once the return has been submitted you will need to wait to see if it is accepted or rejected before making changes.  If rejected, you can go back into the state to delete the forms you do not need.  If accepted, you will have to contact NY state to make any changes.

If it is rejected, I suggest just deleting the estimated tax forms prior to submitting again.On the menu bar on the left that shows. 

1. Select Tax Tools
2. On the drop-down select Tools
3. On the Pop-Up menu select Delete a Form
4. This will give you all of the forms in your return
5. Scroll down to the form you want to delete
6. Select the Form
7. Click on Delete.

Always use extreme caution when deleting information from your tax return.  There could be unintended consequences.
