If they want you to fill in a W-9 then follow the form instructions here :  https://www.irs.gov/pub/irs-pdf/fw9.pdf

Or are you paying a contractor?  If they gave you a W9 with their ssn or EIN you issue them a 1099NEC.

You need to give a 1099Misc or 1099NEC (new for 2020) to anyone you paid $600 or more to for the year. But not to corporations or for merchandise. You send the IRS a copy of the 1099Misc/1099NEC with the transmittal summary form 1096. These are due to the person by Jan 31 and to the IRS by Jan 31.

To prepare W2s or 1099NEC or 1099MISC you need to use the Online Self Employed version or buy the Desktop CD/Download Home & Business program or the separate Turbo Tax Business program.
