I'm not sure if I should file Taxes or not, I was unemployed for all of 2020 but did sell some stocks (only about $400 worth). I'd really appreciate any advice!

I didn't work at all during 2020 but do have a Robinhood account in which I sold some stocks (about $400 gain) and some Dividends (about $15 total for the year). Since this is such a low amount of "income" I'm hesitant to file Taxes because it will cost me $75 for the Deluxe Turbo Tax Filing. I'd really appreciate any advice!
