Sorry--you can no longer get 2014 software from TurboTax; it is not supported, and even if you can find it on eBay, etc. you will not be able to update it to use accurately so it would be useless.
You can get the paper forms and prepare them by hand. It is too late to get a refund for 2014 even it shows one on the tax form. Refunds from tax years earlier than 2016 have now been forfeited. If you owe the IRS still wants you to pay.

Remember to prepare your state return as well—if you live in a state that has a state income tax.
When you mail a tax return, you need to attach any documents showing tax withheld, such as your W-2’s or any 1099’s. Use a mailing service that will track it, such as UPS or certified mail so you will know the IRS/state received the return.
