<prompt> Human: I am freaking out. While moving a few months ago I found a letter that had slipped behind furniture dated last year from a collection agency stating that I owe 20,000 in state sales taxes. I was super confused and made the mistake of calling. The collection agency said they no longer possessed that particular debt and forwarded my call to a law firm at which point I panicked and hung up. Ive checked my credit report and nothing is showing up on there besides my owed student loans and I checked the Ohio Attorney Generals website and entered my info and nothing came up. Ive been getting repeated calls from this law firm but i was advised by my in-laws that its probably a scam and to ignore it. Well Im moved into my new address and I just received a letter today from the same law firm claiming they represent the Ohio Department of Taxation and that I owe 1,800 in state sales taxes. Theres a note saying this is an attempt to collect a debt and that I have 30 days to dispute it. I dont know where these numbers are coming from and Im freaking out. Im an aspiring illustratorartist and I sell artwork occasionally on an e-commerce site the total sales tax collected since I started according to my account is around 30 and in 2014 I did a local art festival as an emerging artist which was basically like a beginner vendor where I sold a couple paintings for cash I think they had me fill out a vendor license? I also do portrait commissions every now and then but nothing thats considered a steady income and most of it is a loss after supplies and expenses. I havent worked since 2015 suffered trauma at my last place of work and am dealing with mental health issues and havent filed taxes since 2016. I am being supported by my partner and my parents. Im not sure what to do or how to go about disputing the debt or if its even real. Please help.  <response>: Call the Department of Taxation to determine if its legit. If it isnt, contact the police. If it is, contact legal aid to get help moving forward.
