I think you mean "investigate" this.    This is a known SCAM.  Do not reply, do not give any information.
They will use any information they get to commit fraud against you.
The IRS will never call you. They will send you a letter if there is any issue.

Whomever called you is just dialing random numbers - or dialing a number they obtained someplace.
It is not the IRS but someone from India trying to SCAM you.
