Get your taxes done using TurboTax

Thank you. I forgot to indicate that I started as a contractor last January 3, 2019 up to March 15, 2019. I signed W4 for the same company on March 15, 2019. Now I'm confused and worried at the same time. Do i need to pay quarterly (divide taxes) from $4000 I earned in total for those 2 months or Do I have to pay the taxes in full this April which believe the 1st quarter for paying quarterly taxes?
