Turbotax web 2020 asked me what I received in the first stimulus payment. Now that we received more $ I would like to know where to find that section to enter the $.

We know that the IRS is already revising the 2020 Form 1040 to include the 2nd stimulus, but that change will entail a lot of re-programing at the IRS and for the tax software programs.  It may be at least a month — or longer— before the forms are changed.  Do NOT be in a hurry to file your 2020 tax return until more is known. Give some extra time to the IRS and the software programmers so that the software can handle the new 2nd stimulus, so that you can get it all by filing ONE time. You will need to visit the recovery rebate section AFTER the form and software revisions are complete in order to do this correctly. It is never a good idea to file too early; filing your 2020 return too soon may result in a lot of extra confusion that can be avoided if you wait and file a little later.

the software does not reflect the 2nd stimulus; when it asked how much you received, only consider the 1st payment until the software is updated.
