Retirement tax questions

I have a large amount in 25c Other forms.   I understand it's for Forms W-2G,K1 Additional Medicare Tax, Form 1042-S, Form 8805, Form 8288-A.  The only one possible would be Medicare Tax, which I don't know that I have?

Where would this amount come from, and how can I work back to check where the input came from?

 

Thanks in advance
