Get your taxes done using TurboTax

Thanks Carl. If i go straight to the IRS site, how much would i know to pay out of pocket by say April 5th for the 1st quarter if my employer has also withheld income from my 1st quarter paychecks? Bc im really only trying to cover the taxes on my stock trades and dividend income and want the credit for the taxes withheld by my employer. 

Second, my state does have income taxes but i didnt underpay them for 2019. Are you saying that since i have to file federal taxes quarterly now for 2020 that that automatically means i have to file quarterly state taxes too for 2020, even thou i didnt underpay my 2019 state taxes?
