You can't not file taxes in any year that you're required to, or you can face serious repercussions. You're required to file a tax return in every year in which you have a filing requirement.
For example, the filing requirements for tax year 2020 are shown in the TurboTax Help article Do I need to file a federal return this year? .
If you fail to file a return for any year when you're required to, you can end up owing not only your taxes, but significant penalties and interest.
Please see the TurboTax Help articles How Do I File Back Tax Returns? and File your 2019 taxes for general guidance on filing past-due tax returns.
