Do I need to amend my (pending) 2019 tax return?

[Eculvey]

I filed my 2019 taxes yesterday. Then I realized that I hadn't claimed, or paid, my supplemental motor vehicle tax. I made sure to pay it today ($259.06). Do I need to amend my taxes to add my car tax?? And if so, how??

@ammend @bobcartax2019 Should I be entering this as a car registration fee or as... @forgot @Help

What state?  Many states do not base the vehicle registration fees on the value of the vehicle.  That property tax is what is entered for the registration fee on a tax return.

If you paid it today in 2020 then you deduct it on the 2020 return next year.
