I filed a amended return 9 months ago. I did not receive the full amount that turbo tax said i would be getting.

Even during “normal” times it takes about four months for the IRS to process an amended return.  During the pandemic and due to the severe backlog at the IRS it is taking much longer—six months or more for many amended returns.  Do not expect quick results from amending.  When the IRS issues a refund for an amended return it will be by check.  They do not make direct deposits for refunds for amended returns.  You can watch for information here:

https://www.irs.gov/Filing/Individuals/Amended-Returns-(Form-1040-X)/Wheres-My-Amended-Return-1

You have to review your 1040-X carefully and be satisfied that it is correct before you submit it.

After that, IRS will make corrections if you messed up.
