Tax Accountant MIA

Hey Mat & Mark,
My business taxes were overstated by $40k+
I’m not certain my personal taxes were ever filed.
My tax accountant is currently MIA.
I’m rcvg tax bills & EDD certified notices, all looking for large amounts of money - which I’m certain I wouldn’t owe had taxes/paperwork been filed correctly/on time.

If corrections/paperwork have been submitted or are submitted soon, will that relieve me of having to make the interest/late payment penalties?

Thank you!
Joanne/CA
