Employee RSUs

Dear Sir/Ms.,

I received RSUs from my company and it went public -- so we converted the RSUs to shares in 2021. I had paid taxes when they RSUs vested on a regular basis. 

 

If we sold some of them, should we just take the difference of the "sale price" and the "vested price" as capital gains ? 

- do we need to file any specific forms ? e.g. somebody indicated that I may need to file IRS form 8949 

 

Appreciate your views. Thanks

AC
