I need some legal advice please!?

So my non-blood uncle has been living in my dads house for going on 5-6 years, I had lived there but as of about a year ago had moved out on my own since I hit 18, my uncle and my dad drink a lot (literally a lot) its slowly taking both of them in a downfall my uncle about a month ago went into the hospital because of it and they found tumors on his brain and his esophogas was basically gone, he was gettin 1200 a month but since it had taken so long he had gotten something like 11,000 in back pay, I believe he was getting it from the srs, around march I found out I was pregnant with my husbands and I's first baby and quit my job being it was construction and I didn't feel comfortable working there, so money got extremely tight and my uncle lent me money to pay for my bills and stuff when it got to last minute and he also had just givin me money since there was times he didn't have money before this and I bought him stuff he wanted and needed, and like I previously stated I no longer live there and haven't for over a year and I got a letter in the mail (my dads mail) not mine) that said I was an alleged perpetrator for abuse neglect fiduciary and something else I think and I don't understand why, I don't know if I truly did anything wrong and if I did I didn't do it purposely can I go to jail for this? I'm worried and probably about nothing I'm just worried information will be amazing and very much appreciated thank you
