Series EE bond into PA 529
I have a series EE bond issued to me from my grandmother that has matured (Aug'21), I was 8 at the time it was issued. I now would like to roll it over into my own children's PA 529s, however everything I've read eligibility wise to do this to avoid tax indicates it would have needed to be issued after I myself turned 24. I'm trying to understand if I cash it and then within 60 days deposit all of the funds into their 529 accounts, will I be hit with the tax bill/need to send in estimated taxes?
Also looking ahead to taxes, anything special I need to know when filing?
Thanks,
