Hi there Kecy2015,
Thanks for joining us in Apple Support Communities! We understand you're seeing some unexpected numbers for a website in your Screen Time report. We're glad you're here, and we can provide some guidance.
To begin, when did you set up the 1 minute limit for that website? Did you follow the steps here:
Set up Screen Time for yourself on iPhone
Is this website currently open in Safari or another browser? If you close the website and the browser app you're using, does that seem to make a difference?
Send over these details, and we'll take a closer look from there.
Cheers!
