this may be a situation where something went wrong when those 2 were imported. There is no telling if the issue is with Turbotax or the W-2 import. you can go back to the W-2 section and see if any lines are in red. that would indicate something is wrong with them. you can try correcting them or delete them and try reimporting. if that doesn't work, you'll need to delete them and enter the info manually.
line 1a of the 1040 should be the total of the box 1 of the 3 w-2s and line 25a should be the total of the 3 box 2
