The TTX program will create the 1040-ES forms only if you owe taxes. Since you're getting a refund there's no need for the program to do that this year.
However, if you want to pay estimated taxes you most certainly can, and you don't need any program to tell you that. You also don't need the 1040-ES either. You can pay your 2021 quarterly estimates on line at www.irs.gov/payments.
