Filed 2021 Taxes with wrong capital gains accounting method, can I amend?

Greetings,

 

As the title suggests, I just realized I filed my 2021 taxes with the wrong accounting method for capital gains. 

 

I've been investing in crypt for quite some time.  I've been using the same tax software to determine gains/losses every year.  I have always used the LIFO accounting method.  Last year, I was playing with the software and noticed an option called "OPTI" and generated a report with that as my method to see what it would look like.  It turns out I submitted that report instead of the LIFO report I generated.  

 

Is it possible for me to amend my return from last year with the LIFO report?  I believe the only visible change on my report would be the total capital gains and the accompanying printout of the taxable events / trades.  I'd like to amend because I have filed LIFO every year, meant to file LIFO last year, and plan to file LIFO in future years ... seems important to be consistent.  I also would have shown less gains last year with LIFO ... not sure how that works, but I definitely paid too much in gains last year because of this mistake.

 

Thanks!
