I completed 2019 tax return using turbotax (Joint filing) and now IRS sent me a letter (LTR 12C) asking "to support the amount of wage or withholding entry of $xxx on line 18d, For 1040". The line 18d in my case is for "Excess social security tax" and it's evident through my W-2s sent to IRS. Should I send them W-2s again? How should I explain it to them?
PS - All W-2s in this filing belongs to only one person in the joint filing
