It's all taken care of. The key thing is the IRS got their money on time every quarter. I mailed off the Q1 form (notice received today was dated Oct 20 btw
) today and filed the Q2 online late. I filed Q3 as well, but it is not late as I have until the end of Oct to file it. Just hope the penalties aren't too bad on the late Q1 and Q2 forms.
