I have made self-employment income from multiple clients that never sent me 1099-K. What should I do?

I understand that all payments over $600 should have been accompanied by the 1099 form but almost non of my clients did it. How and which form do I enter this in?

Just enter it as Cash or General income.  You don't need to get a 1099Misc or 1099K.  Even if you did you can enter all your income as Cash.  Only the total goes to schedule C.

[Opus 17]

If you are self-employed, you are required to keep accurate business records of all your income and expenses and report it on your tax return even if you do not get any paperwork.

A 1099-K form is not issued by individual clients. The 1099-K would be issued to you by payment processors, such as square or Venmo or eBay, if they pay pass through a certain amount of money to you, and the threshold is much higher than $600.  (i’m too lazy to look it up right now.)   If another business hires you, they are required to issue a 1099 – MISC if they pay you more than $600 in a year.   Individual clients who are not businesses, who simply hire you to do a job, are not required to give you any tax paperwork. That is why you are required to keep your own business records.
