I bond purchase AFTER already recieving tax refund

[klebane]

Recently I became aware that one can buy I bonds with their tax return. I alreday filed and recieved my refund.  Is there someway I can still use the amount of my refund to purchase I bonds or must I have opted for this when I filed my return

Yes, you would have had to select the option during the preparation of your tax return. Please see the below help article for more information.

How do I buy savings bonds with my tax refund?

At this point, you could still buy an I Bond on the Treasury Direct website, assuming you qualify.
