Can I collect my social security while I'm still working, even though I turned 66 1/2 this July?

I turned 66 1/2 in July 2023, but I'm still working and don't plan to retire until June 2024. Can I collect my social security now? And what amount of my social security should I set aside for taxes this year?  Example:  Social Security for 9mos comes to about $27,000.
