Schedule K-1

According to my boss, the company I work for (and have a 5% stake as a partner in) had the option to file my taxes on my behalf. He claims that I should not have any liability from this and sent me a Schedule K-1 after I already filed form 1099-NEC.

 

Do I have to file an amended return? He already filed this K-1 form on my behalf and claims I should not have any liability, but also claims that I should file an amended return. When I fill out the information from the K-1 form he filed online, it claims I owe around $8,000 more, even though I already paid around $9,700 in estimated tax throughout 2022 and only have $33,562 reported on my guaranteed payments. Not sure what I am doing and if it is wrong (I'm 23).
