Retirement tax questions

thanks, but I re-calculated the 1040-SR Social Security Benefits Worksheet manually.   I came up with a number  that was $14K higher than the number entered by TT.   I think that is what the IRS keyed in on but I won't know until I get the written response the IRS said they will send.   According the Where's my refund IRS website, I went from a refund to a balance due, 25 days after I filed electronically with TT.   If TT has a systemic problem with their calculation, that troubles me.    The TT help chat is pretty worthless on this topic.
