Will I got to jail for 148.5 violation?

I lied to the cops and the detective’s false report. I made the whole story up. I was robbed by these gangsters and they held me up and stoked my purse and my phone. When the detectives came to ask me about the issue, I told them the same story. My boyfriend was there at the time with the incident. I was having issues with my boyfriend. I was in a verbally abusive relationship, so I was scared to tell him because he has a bad temper and was scared to his reaction. I was out late with friends so I made the whole thing up. I went to the police station because the detectives knew I was lying because of the cameras. They went to the location. I never was there and I was still nervous and scared to tell them after they knew I was lying. Now I'm going to court and don't know if I'm going to be charged with a felony or misdemeanor or go to jail. I'm a single parent at the moment. I just don't want to go to jail.
