Estate tax using Turbo Tax Business

I am the fiduciary on my mothers estate.  I am filling for 2021 and using TurboTax Business 1041.  The Federal taxes seemed straight forward, however, I live in Illinois (this is where I have the estate address).  My mother is from Minnesota and has income from Minnesota (1099 R only <$19K) and Pennsylvania (Royalties on oil leases <$800).  Only 2 states showed up in TurboTax Business (1 for Illinois and 1 for Penn., nothing for Minnesota).  Going through the state taxes, its not clear if I have to file any other forms for each state.  Illinois says I owe ~$500 in taxes which seem odd for the little income that was received in Minnesota.  Penn. does not show any taxes required.  Question:

1. Should I have to file a MN return if the decedent was from MN and I as the fiduciary live in IL where I set up the estate accounts? 

2. Should I even have to file an Illinois return since all of the income was actually earned in MN?  Does owing $500 to Illinois in state tax even make sense when total income was less than $20K?

3. Do I have to complete other forms for each state when the income is only that listed above?

 

Thanks
