My sister had to file an amended return for 2020 after she received updated information from her broker last Spring after she had filed. Her AGI increased by a grand total of $18.00
Due to COVID and staffing shortages, her amended return has not yet been processed.
If the amended return is not processed by the time she files her 2021 return in early 2022, which 2020 AGI should she list? The initial AGI or the one from the amended return?
I suspect the original will be accepted by the IRS computers as long as her amended return has not been processed.
