Can I file an estimated quarterly 2023 tax return now?

TurboTax does not support the filing of estimated quarterly taxes (other than printing and mailing Form 1040-ES).

 

You can make payments at IRS Payments or EFTPS (after registration).

 

EFTPS: https://www.eftps.com/eftps

 

IRS Payments: https://www.irs.gov/payments

 

 

You mean an estimated payment----you do not file a quarterly tax return.  If you want to pay an estimated payment, go to the IRS payment site:

Make sure you keep a record of that payment so that you can enter it when you prepare your 2023 tax return in 2024.
