Khaithue47, this has nothing to do with your 2019 tax return. I assume that this is your own IRA, not an inherited IRA. When you entered the code 7 2018 Form 1099-R into TurboTax you should have indicated to TurboTax that only some of the box 1 amount was RMD ($18,749.51 based on the information that you provided [Edit: actually $12,611.90 based on what you have said below, but that doesn't change any of the other details]), that you moved some or all of the money to another retirement account (or returned it to the same account), then indicated that you rolled over $14,000. I, doing so, TurboTax would have included only $18,749.51 on 2018 Form 1040 line 4b and would have included the word ROLLOVER next to the line. If you did not do this correctly when you originally filed your 2018 tax return, you must amend your 2018 tax return:
