Retirement tax questions

There was another very minimal amount in box 12, but is not enough for it to calculate correctly. There was also an additional line in box 14 besides tier1, tier2 and the rr Medicare. Employer has told me it is covid sick leave. I’ve even tried adding that to gross wages, but still get a small over payment. I’ve tried all the combinations I can think of. Have never had this problem using turbo tax in the past, something must have changed in their software. At this point I’m wondering if it really is a mistake with the W2 or turbo tax?
