@Brianna31 What both @Michelle53 and @Lisa723 said is correct. AirBnB wouldn't have anything to do with collecting federal taxes. They are collecting whatever local and state lodging and other taxes are owed to your municipality. They certainly aren't submitting any kind of tax revenue to the IRS.
Did you file a Schedule E with your tax return? That's the schedule for rental properties. If you didn't, it means you didn't report the income you made, and that's why the IRS is calling.
It must be a substantial amount if they are levying your bank account.
A CPA or Enrolled Agent should be able to help you with this.
