In TurboTax Premier Desktop, I am able to report Oregon Subtraction Code 315.
Report the IRS form 1099-INT as follows:
- Down the left side of the screen, click on Federal.
- Down the left side of the screen, click on Wages & Income.
- Click the down arrow to the right of Investments and Savings.
- Click to the right of Interest on 1099-INT.
Enter the amount from Box 3 Interest on US Savings Bonds and Treasury obligations.
The interest is reported on Oregon OR-ASC Section B Subtractions.

The interest is deducted from the Oregon OR-40 income tax return.
