There are two tyupes of slur in play here. One is where notes are tied (ie, held and not replayed) and then there are legato slurs - different notes to be both/all played legato. Where the last of a legato phrase is marked as staccato or with an accent (editions vary in this usage) the last note is held only briefly and not for it's full value.
Step one is to identify all the held notes. There are a lot of them and they are all marked (ie, where there are two notes in a chord and both of them are held, both of them are marked - where only one is held, only that one is marked).
Sitting down with the score and listening several times to decent performances will assist. You may also find it useful to mark the score so that what is meant is clear to you.
Your fingering needs to accommodate the held notes without the use of pedal.
As visitor said in your thread about the last movement, this short little movement is full of challenges and should not be taken lightly. It is important to get the phrasing, notes and fingering right from the outset.
