I have reciepts from this year that I paid on rent can I use these for tax breaks

RENT

There is not a rent deduction or credit on your Federal return.  If your state has anything for renters you will be prompted to enter your rent info when you complete your state return.  As far as I know, the states that have anything for rent are Arizona, California, Connecticut, Hawaii, Indiana, Iowa, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, New Jersey, New York, Rhode Island, Vermont, Washington DC, and Wisconsin.

For the State of Missouri property tax credit WHERE does a renter upload receipts for rent paid?

You cannot upload receipts to your tax return.    You just need to manually enter the information about the rent paid.   Did the landlord provide a certificate of rent paid?
