Retirement tax questions

Oh and by the way, this tax issue is for my daughter who is a student and had no income for tax years 2020 and 2021, so she didnt file returns at all for these years.    So previous question should have been....should she file a return for 2020 and 2021  and submit the form 5329  or could she just send in form 5329 for these years.  Thanks .
