I am using the Mac version and had the same problem. Clicking on the tabs at the top did not work for me either.
However, if you save and quit TurboTax reopen TurboTax and navigate to the first screen where you see the deductions tab, it will work when you click on it.
I hope that helps anyone stuck with this rather silly bug.
Dear Intuit -I had my family taxes open, which I had finished earlier, and was working on my teen child's taxes which consisted of a single W2 (same employer, new name, new EIN and new state WH ID), a negligible state refund from last year, an imported e*trade acct with just dividends, and negligible interest from Bank of America which I typed in myself. Hope that will help you find this.
