Took a 401k loan out but have not received 1099 or what ever I supposed to get

You do not get a 1099R for a 401k loan.   You get a 1099R if you took money out of a 401k and did not pay it back.   If you paid it back there is nothing to enter on your tax return about it.

A loan is not taxable income because you promised to pay it back.  If you ever stop making payments any outstanding balance will be converted into a distribution and you would get a 1099-R at that time.
