I received some tax forms and I wanted to start entering them in Turbo Tax. However I am not sure if I can receive all the forms in time to file my tax return in April. Is Turbo Tax's "file an extension" function still available after I start working on "2023 Tax"? And if it is, after I file an extension, will Turbo Tax wipe out what I've entered for 2023 Tax or will I be able to return to where I was and continue to finish 2023 filing later? Thanks!
