turbo tax software refund error

I filed a 1040 through turbo tax on 2/18/21 with a refund of      $1903

I received the refund on 2/24/21 from the IRS of                           $1903

Today I incidentally was looking at turbo tax and it

now shows a refund of......................................................................$5141

This is a difference of  .......................................................................$3238

I looked at my 2/18/2021 filing and it is the same as my today (3/8/2021) turbo tax.  Nothing has changed except for the refund amount.

What went wrong and now how do I get the additional $3238?
