529 contribution limit

[happysue19]

I set up a 529 account (Ohio) for my Grandson.  I contributed $75,000 for 2025, but want to contribute a total of $150,000.  

What is the next step?  When I file my taxes for 2025 do I report this amount? 

Can I contribute the full amount in 2025 or should I contribute the other $75,000 in 2026?

the way you describe what you have done, there is no federal limit or deduction or credit. everything is at the state level except the need to file a federal gift tax return since the amount exceeds the annual exclusion

ohio allows up to a $4,000 year deduction (against ohio taxable income) each year. any excess contribution is carried forward. nowhere do i see $75K or %150K mentioned

there is a section in Turbotax under education for ESA and 529 QTP  but that's only if
