Has anyone gotten a 2645c letter ?

[Mike9241]

a letter that is simply saying the IRS has received something from the taxpayer but has not acted on it yet.

what? any of the following

The IRS inquiry letter does give a few options as if to jog one’s memory:

Correspondence
Telephone inquiry
Payment
Form
Response to our inquiry or notice
Penalty abatement request
Installment agreement
Other

letter states that the IRS will contact the taxpayer within a specified time frame (usually 45 days)
