No. E-filing of Tax Year 2020 returns closed in October; TurboTax phone apps are an extension of TurboTax Online. At this time, you must file a paper return; you'll need TurboTax CD/Download 2020.
Do you have a PC or Mac laptop and a printer? If so you don't need a desktop for TurboTax CD/Download, just a way to install it on your laptop (CD/DVD drive, download to laptop or flash drive, etc.)
