I never had to pay any estimated tax since my employee withholds tax every year. 2020 is the 1st year that I need to pay <$1000 federal tax. When I filed my tax for 2020 with TurboTax, it automatically generated 1040-ES for me. I don't believe I need to pay the quarterly estimated tax since my employee is withholding tax on my W4. What can I do to make sure I don't need to pay 1040-ES?
