Does it make any difference if there's no value in box 14 of W-2 when there are vested RSUs that sell to cover?

I've been all over TT reading about RSUs, Sell to cover, etc. I get close to understanding the get more confused.  I don't have an entry in box 14, but do have a $ amount in box 12c along with a "V".  Same thing/good enough?

I've imported from eTrade and have a few RSU STC transactions with my own sale of the remaining vested lot of RSU (later dates) along with various ESPP sales.  It sounds like it might be easier/less confusing to delete the eTrade import and enter every transaction manually.  

There appears to be a bunch of RSU related articles throughout the TT Community.  Is there a specific one or two that address most things or walk a rookie like me through the process?  

Thanks -
