Turbotax doesn't support online prep or e-file for 2024; if you need to file 2024 and don't want to deal with downloading desktop software for 2024 and printing forms then check into other alternatives such as FreeTaxUSA that support online filing for back tax years - IRS e-file closes Dec 26th so you may still be able to file online thru them (not tried them myself).
