Estimated Taxes

Hi!  I have been paying my quarterly estimated taxes based off the information I received when completing my taxes last year.  I am expecting to have more income however this year - is there a way to estimate my taxes with the increased income so I am submitting the correct estimated quarterly payments?

 

Also, on tubotax it shows that it is estimating I get a return this year, with nothing else changed?  Is this because I am likely overpaying on quarterly estimated taxes?  Sorry if these questions don't make sense, estimated taxes just leave me very confused!
