What am I looking at if I was charged with filing a false report?

I made a report about a possible intruder in my garage due to damage to the door and car doors being found open. I realized that the damage had come from my vehicle. When the police arrived, I panicked and said I hadn't hit my garage as I had been drinking that day and was worried about DUI charges. I came clean after a few minutes and was charged with filing a false report. They claimed that I staged the entire story to cover up the damage to the garage, but my initial intent was to have police check for a possible break in. It wasn't until later that I realized the damage had most likely come from my vehicle, and I was honest with them after a few minutes. Is there any way to estimate how severe the charges might be? All I know at this point is that I was charged with a misdemeanor.
