I did not amortize my bread route the last 2 years, I am interested in doing it i know it is under 197 but what do i do for the last 2 years? do i have to file an amended return? thanks for your help

Yes, file amended returns for the years in question.  You can amend both years using TurboTax.  If you are using TurboTax Online, 

1. scroll down the page to Your tax returns and documents  
2. click on the drop-down arrow if necessary
3. when you log into your account, scroll down to the bottom of the page where you will see the various tax years during which you filed a tax return through TurboTax. 
4. select year 2020, as that is the year it appears you want to amend,
5.  select "Amend, Change Return" near the bottom right of the Tax Home page, 
6.  after selecting Amend 2020 return, follow the steps to begin the process.

To amend your 2019 return, follow the same process as above.  

Note:  Any changes you make to amend your federal return will automatically be transferred over to your state return. If you’re already amending your federal, you don’t have to make any changes to your state, unless you’re making state-specific changes.
