Another Question:
Mother in Law sold her house in 2019 at 100 years old. No income other than SS benefits-less than taxable amount. Capital gains less than 250K. In the closing, there's a piece of paper saying it is an alternative form 1099S. (Date/Proceeds/Address). We did not receive an IRS form that looks like what is shown on the IRS website.
We did not file a 2019 return for her. Can we (more importantly, should we) do that retroactively?
