Mid-year change to quarterly filing

I worked at a W2 job the first 7 months of 2024. Now I’m independent. I don’t expect to earn a lot of revenue this first year; however, I will have CDs maturing and other interest income during this second half of 2024. My question is — if I have paid enough through withholdings Jan-July to cover the taxes on the rest of the year’s income, do I need to do anything at each quarterly deadline for this year? I do not want penalties for not paying on the interest income in the quarter it is earned. But I have prepaid. Thanks!
