Retirement Income

I've been using TT for years and this is the first time I've been stumped.  I'm sure it must be something I've entered but I'm darned if I can figure out what I've done!  In the income summary for retirement, it's showing a taxable amount greater than the income amount.  We did pay off the balance of the Covid-19 distribution we took and I entered that where asked.  We did not get a 1099R for the payback.  Unlike other entries, I can't click on the amount to see what it consists of.  The only income under retirement we have is my husband's pension, for which we did receive a 1099R and I listed, and my social security.  Where is that extra income coming from?

Thanks!
