As per this passage in my reply:
"I discovered that when my sister had filed her taxes in 2023 to declare some money she had spent from her Pell grant for non-education expenses, she had not listed herself as a dependent since our parents did not file taxes that year (i.e., TurboTax asked her if anyone will claim her as dependent in 2023, and she selected no since my parents had not intended to file at the time).
I'm assuming that's what may be causing at least one of the errors to show up, since she is now listed as a main filer who is not dependent. In actuality, she is."
Is this also what caused my parents' 2024 return to be rejected, or is it simply the mistyped SSN?
