Please review the link below to assist you in entering in your second vehicle on your T777 form:
How do I claim two leased vehicles in a year on my T777 form?Is there a way to add a third vehicle? We have been able to enter two vehicles, but are unable to enter expenses for a third. This option is available in the online version, but seems to be unavailable in the desktop version. Please help, as I need to add 3 vehicles. Thanks.
There is a limitation to report two vehicles in the employment expenses sheets using TurboTax Desktop/Download products.
If you still want to use the TTD, you will have to print the return and attach another form for T777 with the third Vehicle. Unless you want to switch to an Online product.
You can report up to three vehicles using TurboTax online products.
I hope this was helpful
