How do I complete the process to submit a payment plan after submitting the federal tax return and requested a payment plan?

I e-filed my federal tax return for 2023 with Turbotax,  and selected the option for a payment plan. I received an email from Turbotax, that my federal tax return was accepted by the IRS,  but I got no email yet from the IRS or anything from turbotax to indicate what is next.

 

Can someone please advise what should I do next? I filed the return on April 6th, and as of today April 11th, still no email.

 

Thanks
