prior year returns

[Madrigal49]

My sister came to live with me on May 2019 and I didn't claim her.  Can I redo my taxes for that year ( she's on SSI) and what form do I need?

You can amend back three  years to receive a refund, so you would be able to add your sister to the 2019 return. Before doing so, you should confirm that she meets the criteria for a qualifying relative.
