we always use this laptop for our taxes, so TurboTax. Disk-wise
Independent of your experiements with Linux, it may be a good idea to switch away from turbotax. They've been lobbying to make filing taxes harder for the past 20 years.
More relevant to the Linux discussion at hand, they're locked into a specific operating system, whereas the alternatives are much more modern and work just fine in a regular web browser. I've had good success across three states with freetaxusa, personally.
