@blueandgreen, It’s always best to look up the regulations yourself, not guess at them or let other people guess for you. FL home schoolers are required to file a Letter of Intent each year, keep a portfolio for each student, send the district a yearly evaluation (test results or a report from a certified FL teacher, etc.), and inform the district when they’re done home schooling. FL home school regs can be found at:

You’d have to contact the colleges you’re interested in to find out what documentation they might want. The Univ. of FL, for instance, wants a completed SSAR form (Self-reported Student Academic Record) from home schoolers which they validate after students complete high school. They don’t say whether or not that validation includes contact with your home district. http://admissions.fsu.edu/freshman/admissions/requirements.cfm
If you applied to college in NYS a GED could be required if you couldn’t satisfy the other proof of high school equivalency requirements (which require you to abide by your own state regulations), so how you handle this situation depends on where you apply. http://www.nyu.edu/admissions/undergraduate-admissions/apply/transfer-applicants/instructions/high-school-preparation.html
If you’re not a senior now, I think your best options are for your parents to submit the appropriate paperwork to your district or plan for you to take the TASC (formerly GED) just in case you need it. Good luck.
