"I contributed $3375 for 9 months of the year before I had employment" - what does this mean? Were you covered by an HDHP policy for those 9 months? Did you make direct contributions to your HSA not through an employer?
If you contributed $3,375 directly to the HSA (not through an employer), then this amount should appear on line 2 of the 8889. Any amounts (like the $1,125) through the employer should appear on line 9 of the 8889.
Most taxpayers do not realize that contributions made through the employer are not explicit deductions on line 12 of Schedule 1 (1040), but are instead removed from Wages in boxes 1, 3, and 5 before the W-2 is printed. The reason that contributions made through the employer are not reported on line 12 of Schedule 1 (1040) is because they were never in your Wages in the first place.
"Hopefully this is enough information for you to track the bug down." - there is no bug in TurboTax. Ask your employer if they removed the $1,125 from Wages when they printed your W-2. If so, then your W-2 is correct and your return is correct.
If your employer did not remove the $1,125 from Wages in boxes 1, 3, and 5 on your W-2, then you deserve a corrected W-2 because your employer did not complete the W-2 correctly - please show them the Instructions for the W-2 for code W on page 20.
