As an IC who got a sign on bonus in January, do I pay quarterly taxes on this? How much and to where? Employer said this will be on a 1099 at end of year.

I am a physician that officially started working in August and my sign on bonus is 4k per month starting in Jan 2019 (thus has had 3 4k payments to me). I will get this through June.   Employer said income will be reported on a 1099 for 2019. No idea what/where to pay.

Are you a W-2 employee otherwise?  Or is all your work considered self-employed?

Yes, and you can set up estimated tax payments in TurboTax by typing the words estimated payments into the Search window on the upper right to get to that interview.  You'll receive printed payment vouchers to send to the address on the vouchers along with payments on the date shown on the voucher.

If you use the desktop/CD version, oyu'll find this interview under Federal Taxes, Other Tax Situations, W-4 and estimated Taxes.
