Get your taxes done using TurboTax

Ok so fanfare for my quarterly estimated figures i calculate, i can ignore or exempt the income and withholdings from my paycheck (presuming my w4 withholdings are perfect) right?

 

Then i only calculate my quarterly estimated taxes on my expected dividends and capital gains on stocks i anticipate earning in 2020, bc nothing is withheld for that income. Is that correct?

 

I have no other income besides my paycheck  and dividends and capital gains on stocks.
