In my case, it took SSA over 120 days to report the unpaid amount to IRS.
In about 6 months, I received a penalty notice from IRS of not reporting the SS amount, I then had to present to IRS the cancelled check and other doc to prove that I was innocent. Finally in about 6 months, I received a letter of clearance from IRS to state that no tax was due.
Good Luck!
