O_o-22's journey

I recently filed for unemployment in Michigan after losing my primary job, which was my main source of income. This job had an hourly wage plus tips, but my earnings fluctuated significantly based on the time of year and the number of weekend shifts I worked. I still have a second job that is a 1099 gig, which has been greatly affected by COVID-19, earning me about $100 a week, while my previous job could bring in $400-700 weekly. When I filed my claim, I calculated my earnings based on the highest earning quarter from the past five quarters, using my paystubs to average my earnings. I didn't include the income from my 1099 job because I thought it wouldn't matter for my unemployment benefits since I'm still working there and it doesn't count as UI covered employment. However, I have some questions about my calculations. Did I do it right? Should I have included my 1099 income even though I’m still employed there? When they refer to quarters, do I just look back 12 weeks from when I stopped earning, or is it based on the calendar quarters? I certified my claim today but I’m considering calling to amend my answers regarding my 1099 income, just to be safe. Any advice from those who have been through this would be greatly appreciated!
