State tax filing

The apportionment of NYS income for a S Corporation is done on the tax forms for the business, specifically the CT-3-S - Part 3. Shareholders pay New York tax on their pro rata share (in your case 100%) of the S corporation pass-through items of income, gain, loss, and deduction that are includable in their federal adjusted gross income. Only nonresident shareholders and part-year resident shareholders pay tax solely on the S corporation items derived from New York sources, which is determined at the corporate level.

However, since you are a NYS resident, your K-1 will have pass-through items that are 100% derived from NYS. In this case, you should not need any adjustments on your NYS return. 

If you need to make manual adjustments, the A-201 adjustment is entered under the TurboTax screen Changes to Federal Income.

You can get to this screen by following these steps in TurboTax:

1. Open your return. 
2. Click on state on the left hand side. 
3. Click continue through your interview questions until you get to the page Changes to Federal Income. 
4. Scroll down and go to Start under Partner, shareholder and beneficiary adjustments.
5. You can enter any additions on the screen Enter Any Partner, Shareholder and Beneficiary Additions. Your input should list the modification code and amount. 
6. You can also then list Any Partner, Shareholder and Beneficiary Subtractions on the following page.
