As a 36 year old ($7,500), will this be seen as over contributing to my Roth IRA?

If I buy over $7,500 in VOO shares? I did a Schwab check deposit and the funds are now available. $7,500 for this year but there was some left over balance from last year. I just feel like something is wrong if I go over $7,500 say someone deposits years in a row and finally realizes they have to buy, they can buy for $30,000 one year and that’s ok? thanks!
