What form are you trying to fill out? Are you using an old version of a W-4?
Here is the 2020 version you need:

And....if you have not had any tax withheld all year and expect to owe at least $1000 at tax time you will be subject to penalties. You might want to make an estimated payment directly on the IRS site.

If you do that make sure you enter it when you prepare your 2020 tax return. Post back then to get help with entering the estimated payment.
