TurboTax Deluxe won't allow me to enter personal property tax for my car during the interview process?

Are you using TurboTax Online?  or desktop?    How to clear your cache

What happens when you try - are you in the Personal Property section

No, I'm using Deluxe downloaded version.

After completing Car Registration fee and finishing that, I get a pop-up window that says something went wrong and to go back and review last entry. When I go back it takes me to the Summary of where I'm at and if I select Update the Property Tax option I get the error message again.

I'll try cleaning cache, but appears to me to be a programming glitch.

If you are using the desktop version:

On the top bar do to Federal Taxes

1. Deductions & Credits
2. Scroll down to Cars and other things you own
3. Select Personal Property Tax
4. Post the tax

I got there, but it still would not allow me to enter a number.

I double click and went to the form and got it entered that way.
