Estimated tax

Hello,

 

I've got unexpected income this year, from which income tax had not been withheld. I estimated how much tax I need to for it, and need to pay it now. 

I 'd like to use my instance of the TurboTax Premier 2019 desktop app, so that it will be automatically included in the calculations when I prepare the 2020 return next year.

 

How can this be done?

Thanks
