Are you referring to making quarterly estimated tax payments for 2018? If so, the date for making the final quarterly payment for 2018 has long passed. That date would have been January 15, 2019.
If you WERE required to make quarterly payment for 2018, please make a payment as soon as possible. You'll be penalized for late payment and interest.
I'm linking you to the IRS publication that explains making estimated tax payments, due dates, how to make payments, and worksheets to help you calculate your estimated tax payments.
For 2019, you "should" have made 3 quarterly estimated tax payments for your business. Again, you need to make payment as soon as possible. Underpayment penalties and interest can be significant.
