You need to pull reports from somewhere. Credit karma is good for monitoring changes but FAR from reliable. Just pretend like you can't see the scores... My CK scores are about 50 points lower than my FICO 08 scores.
LOL And mine are 50 points higher on CK. But to the OP, I used CK to view my credit report on Equifax and Transunion. I was able to start cleaning it up from there. Look at the 700 in 18 months post and get My Fico 3B if you can. You will get all 3 reports each quarter. I started mine right after if filed and should get my next report a week or 2 after discharge. It gets better.
