IT act sec 54GB exemption query

hi

I have a query.

I sold my personal residential property before 31st March 2021 and invested the said proceeds in a LLP as partner capital contribution. I as Partner in LLP have 50% shareholding. LLP is startup recognized and is incorporated in year 2017.

please let me know will I get tax exemption under section 54GB in my personal ITR filing? if yes, can you handle my ITR filing for 2020-21?

if yes, what's your fee? what documents are required to furnish ?
