ITR Filing issues

How many years of ITR are required. Due to covid last year and the recent glitches, last year is not yet filed. can it be filed simultaneously . What are the options available

3 years ITR are required to apply for an education loan. Lenders will also accept 2 years ITR returns. Filing ITR returns simultaneously will not be looked at favorably, though there could be some consideration given to the current scenario. Having said that, it is obviously better to have your ITR done rather than submitting an application without ITR filed.
