To check how many returns you have used in TurboTax CD/Download, select View>Summary>Return Counter Summary from the top menu.
Is this correct for 2022?
I would suggest the Standard version of the software because it offers you 8 return above $25000 and up to 12 more under $25000 for students.

Tips: Quebec is the only province that requires you to file a provincial tax return. Elsewhere you file with the CRA only. Also, you are allowed to do up to 20 returns per computer as per the CRA.
It's mostly still the case.
You can NETFILE up to 20 returns in either TurboTax Online or TurboTax CD/Download, but if you have to do that many returns, it's usually more economical to use TurboTax CD/Download.
TurboTax Standard CD/Download still comes with 8 returns for incomes above $25000, but the remaining returns for under $25000 are not limited to student returns only.
