what Turbo Tax do I need to work with a new Mac Book Air with a M4 Chip

For 2024 or next year?  If you have a new Mac any Turbo Tax program or the Online version should work.

2024 Turbo Tax Desktop Download System Requirements
Windows 10 or later or Mac OS Ventura 13 or later (newer). This one says Sequoia

any desktop TT 2024 flavor will work as long as Mac OS is > 13.  you should select the version of TT for your needs as the functionality differs, and check whether free state program included (not e-file that costs extra), see grid on the Intuit purchase page; check authorized retailers for pricing also (list below; Amazon etc) but I think a lot of the discounts normally offered earlier in the year may have ended.
