Form 1099R Code 1M Box 7

Hi there, 

 

Trying to get a start on my taxes and ran into a snag.

 

I was employed by Company (A) up until 2018 when I was fired. I had a 401k in it that I contributed to regularly from my paycheck.  A year or so prior I had taken a loan out against it (at the time it was necessary and the repayment wasn't an issue).

 

I still had money left in my 401k as far as I knew.   When I was terminated I didn't understand the payback options, and was under the impression the loan would be paid back from the 401k.  I didn't do anything with it, but today recieved a 1099R form from them

 

The form says 1. Gross distribution 2250.00 2a. Taxable amount 2250

 

7. Distribution code(s) 1M

 

I plan on talking to a professional, but I'm not exactly in a great place financially, so I'm at a loss on how to handle this.  Thank you for any clarification you can offer
