Tax filing question

Hello guys,

I have a question and hopefully you can help me,

I just discovered that I haven't added the crypto currency income to my tax filing for the last two years in New York. I had an issue with logging to my Coinbase app, but now I'm checking it and found out that I had gained $1500 in 2021 and lost $850 in 2023.

I didn't file for this year tax because I didn't work and spent the year studying for my PhD program.

Should I file and add these in the remaining filing days of this year?

I appreciate any advice, and I'm sorry because I'm new to this field and my knowledge is limited.
