Self reporting & Official SAT/ACT reports

Hi,
I just finished and submitted all my college applications. However, I am very confused on the concept of sending my test scores in.
So, I reported both my SAT & ACT & 3 AP tests to every college I applied to, not knowing that I could alter this for each school. If I wanted to only send say, my SAT report to one school and not my official ACT report, would they still consider my application? Or since I reported all these scores, I would have to send every one I reported in (which is fairly costly).
Also, can I just wait until I take my AP tests in May before sending a official report in or since I also self reported these, I would need to send these as well?
p.s. my sat is a 1200 (600&600) and my act is a 26 (28 m, 27 e, 24 grammar, 26 science) so they are relatively the same composite score …
Thank you!

Just a question does it matter for uc schools wether you send them your ap test score or does it not affect your chance of admission if you chose to not send them
