Try this.
On the "State and Local Tax Refund Summary" screen, don't click the Edit button. Just click Done.
The next screen asks if you took the standard deduction or itemized deductions in 2017. If you took the standard deduction, your refund is not taxable. Just select "I took the standard deduction" and click Continue.
If you itemized deductions in 2017, select that option, answer the question about whether anyone claimed you as a dependent, and click Continue. The next screen should ask whether you have a copy of your 2017 tax return.
If you don't get that question at this point, what screen do you get when you click Continue on the screen that asked whether you took the standard deduction or itemized deductions in 2017? What is the title or heading on the screen, and what does it say?
