recovery rebate credit worksheet

I filed my taxes 3 weeks ago. Got a refund. Now since then,the Turbotax program has updated  and it says my refund is much higher. The only new question it asked me was line 19  E.I.P. 2 amount, which is 0.   I didnt get one.

E.I.P. 1 was already entered,$408   I had some unemployment payments also in 2020 that were previously entered.  WHY would the program say my refund is much higher now? And would I need to Amend ?
