There is a 6 digit identity protections PIN required by the IRS for those who have encountered identity fraud in past years. Is that what is being asked for?
What's an Identity Protection PIN? The IP PIN is a six-digit number assigned to eligible taxpayers to help prevent the misuse of their Social Security number on fraudulent federal income tax returns. An IP PIN helps the IRS verify a taxpayer's identity and accept their electronic or paper tax return
You should have received a notice from the IRS with that PIN if that is what it is asking for. If you don't have it, you will have to request it from the IRS when they start taking phone calls again.
