Why am I not getting more on this years refund then last years and I worked way more

If you worked more and made more income, it is possible that you are in a higher tax bracket. It is also possible that you lost credits due to a higher amount of income. 

Additional reasons for decreased refunds are:

• Less income tax was taken out of your earnings
• You were in a higher tax bracket due to earning more money
• You child turned 17 and no longer eligible for the Child Tax Credit and are now receiving the Credit for Other Dependents
• You no longer qualified for the Earned Income Credit
• You paid off your student loan and cannot deduct any student loan interest
• You are no longer eligible for education credits
• You took on an additional job
• You sold investments
• You had a distribution from a 401k that was not related to Covid-19
• You had a change in filing status

If you would like to reevaluate your income tax withholdings, you could enter your information on the W-4 Withholding Calculator to get to your desired result for the next tax year. 

Your tax refund is a function of the difference between your actual tax owed and the amount of money you pre-paid toward that tax.  It has nothing to do, directly, with how much you worked.  It's not a "prize" for working, it's simply a return of your own money that has been sent to the government to ensure your taxes are paid.
