When the Profile Menu appears, select Practice under the Pause tab.
Select Putting Practice.
You must sink 5 putts in a row, which means 1 putt each hole from wherever you start (randomly ranging from 20+ feet to 120+ feet away!)
Putt Preview is your friend here. After eyeballing a possible putt lineup, hold
to execute a Putt Preview that shows where your putt will go if you hit it perfectly. It's likely the preview line won't hit the cup, so thankfully you get unlimited putt previews!
Keep adjusting your shot's trajectory again and doing previews until the line gets in the hole.
Next comes the art of actually making a decent putt. SLOWLY pull back your club stick until the swing meter hits the target % marker, then push up the stick as straight as possible to get the desired effect. If your blue swing line in the lower right corner is too angular or curvy, your shot will likely be off.
As long as you never use the Place Ball
feature and never take a Mulligan, the achievement will pop after your 5th consecutive 1-putt hole.
