Does my W-2 withholding cover my side income?
Usually not. Paycheck withholding is sized by your W-4 as if the paycheck were your only income, so tax on side income lands on top of it unpaid.

Either works. The IRS treats withholding as paid evenly through the year, so raising it can replace quarterly payments and even fix a late start.

Yes. Withholding and estimated payments both count toward safe harbor. Estimated payments need to arrive on time each quarter to fully protect you.

Interest starts on the shortfall from the day it was due and grows daily. Pay it as soon as you can, not at the next deadline.

The distribution is taxable income and the tax may be due this quarter. Check the safe harbor rule first because it may mean nothing is due until April.
