Which is the correct way to report excess 401k contributions in 2018 ?

I see some say to enter it under Misc Income and some say to enter it under Retirement Plans and Social Security. Is there a preferred way to do this in Turbo Tax 2018 ?

I got the excess amount back as a check in  March 2019. I did not get an amended W2 or 1099R.

Also TT keeps running smart check complaining about the excess 401K contribution.

Thanks
