The return is already in. Doing that return over again is not the next work. The year you are standing in is the next work.
The estimates for the year you are already living in are the work that is still alive. Publication 505 is where those amounts get figured. Due dates are not listed on this page, because another desk owns that calendar, and a safe harbor share is not quoted from the publication either.
Beside those estimates, close the month you are standing in. A closed month is how next April turns into an ordinary morning instead of a second scramble. Bring the morning you actually have. A pile of years that never went out is a different question from this one.

Reading the morning after an acceptance is the work here. It stops short of an audit, a review, a compilation or an opinion on your statements. There is no CPA license at this desk, so those belong with a firm that holds one. A letter gets explained to you here, never answered on your behalf. A hearing about a balance you cannot pay is representative work, and it lives elsewhere. Everything else that bounds this desk is kept on the disclosures page.
Write which morning you are in, and whether estimates for this year have even started. That note is the whole offer on this page.
If you came here for a rate, it is not waiting further down. The IRS pages linked from the balance page are where the arithmetic stays.
Say what you think the next step is, even if you are only partly sure.
You will be talking to the Steven Palmieri practice.
