iPhone 7

Hey rosemarie15,

Thanks for using Apple Support Communities! I understand you're running into an issue unlocking your iPhone with your passcode.

I recommend checking out the resource below, this addresses what to do if you've forgotten the passcode of your device, or if your device is disabled due to the passcode being entered incorrectly too many times.

If you forgot the passcode for your iPhone, iPad, or iPod touch, or your device is disabled

Thanks again, and have a great day!
