Forgot to Put the Payment Made at Extension into my Tax Return, what do i do?

Hi, I e-filed tax return with the desktop turbotax, but after filing, i realized that i forgot to put down the payment made when i filed the extension. 

I requested the extension on 07/15 via IRS website, along with a payment. However, i forgot to put that payment amount into TurboTax, such that the form 1040 schedule 3 part II item 10 "amount paid with request for extension to file" is blank. 

What can i do to fix it so that IRS knows that I've made those payment towards my tax owed for 2019? 

Thanks!
