how to file M-4868 in MA?

I already file the Federal 4868, but I do not know whether I need to file the MA state extension and how?

I need to pay $4500 of the state tax for 2022 and already paid the State IRS tax of $5000 for 2022. No tax pay for 2021.  Would you mind helping me with where to put the $4500 and $5000?

I am confused that since I already paid the 2022 tax, need I to fill out the extension M-4868? If I need, How?

The full amount of tax due reported on line 7 must be paid by or before the original return due date. If there is no tax due on line 7; no further action is needed for the extension. If there is a tax due on line 7, pay online at mass.gov/masstaxconnect or use the voucher below. If at least 80% of the tax due for the taxable year is not paid by the original return due date, the extension is considered null and void, and penalties and interest for a late return and any late payments will be assessed from the original due date of the return.
