Refund in treasury bonds

[sacramentotaxfiler]

I chose to have part of my tax return to be paid in I series bonds. I recieved a $500 bond check 2 weeks ago but I requested $1500 total. In previous years, I’ve always received the entire portion of the return in bonds together. Separate checks but same day. I figured since they are ordered together they are shipped together? It has been 2 weeks and haven't received the remaining $1000.  Has anyone received their bonds on separate days?

Once your return is filed, TurboTax has no control over the processing of your return or the release of your refund.

Here are a couple FAQs to track your refund:
When will I get my federal tax refund?
How do I track my state refund?
Why does Where's My Refund say "approved" but TurboTax still says "accepted"?
